Final answer:
d.)Ace is incorrect; the contract is enforceable even though it is indefinite.
Step-by-step explanation:
The general rule is that for a contract to be valid and enforceable, it must have certain material terms, such as the parties involved, the subject matter, price, and performance terms. However, there are exceptions to this rule. In this case, the fact that the agreement between the State of Indiana and Ace Construction Company lacks specific details such as the exact work to be done, quality standards, and the time for completion does not necessarily make the contract indefinite and unenforceable.
Under the doctrine of promissory estoppel, a party can be held legally responsible for its promise even if the promise lacks material terms. This doctrine is based on the principle that if one party reasonably relies on another party's promise to its detriment, enforcing the promise is necessary to prevent injustice. In this case, the State of Indiana can argue that it relied on Ace's promise to perform the repair work and incurred expenses or suffered damages as a result. Therefore, the contract may still be enforceable despite its indefinite nature.
